The TA1 sensor requires 3-wires for power and communcation with a TS200(H); as shown 

in the diagram above. In many situations you will be able to simply mount the TA1 sensor 

on a wall and use the provided 10K internal temperature sensor to detect the temperature 

at the desired location.

Follow the guide on page 3 for alternate installation options for the TA1 sensor. The TA1 

sensor can be installed at a maximum distance of 500' from a TS200(H). A 10K external 

temperature probe can be connected to the TA1 sensor up to 100' away.

We always recommend using a Pelian certified external temperature probe. Contact your 

local Pelican Wireless distributor for assistance.
